Unveil the world’s most breathtaking and most valuable jewels – and see them reimagined as absolutely unique pieces of art with Gem Boutique PA.
Gemstones have been symbols of power, wealth, and beauty for centuries. But above their beauty and brilliance, some of these stones possess a quality of scarcity and intrigue that cannot be substituted by the carat. These are natural works of art—constructed over millions of years and treasured by royals and collectors.
Whether you are a gemstone collector, an investor, or someone who wants to own a special fine jewelry design, this data gives the world’s top 10 most expensive gemstones and how Gem Boutique PA can help you create custom jewelry from your selected gemstone.
1. Blue Diamond – Up to $4 Million Per Carat
Blue diamonds are of the highest quality not necessarily because they are blue but because they are rare. The colorful appearance to them is due to tiny impurities of boron. For example, the Hope Diamond. Up to $4 million per carat, these are truly the most expensive stones on Earth.
2. Pink Diamond – Up to $1.2 Million Per Carat
Dreamy, ethereal, and mysterious, pink diamonds are mostly found in Australia’s former Argyle Mine. The fact that it has closed down has contributed to the value of the stone as an investment. Depending on the saturation and colour intensity, the stones are even more valuable and expensive than blue diamonds, thus being one of the most expensive gemstones.
3. Red Diamond – Up to $1 Million Per Carat
Red diamonds are so rare that naturally, fewer than 30 exist. They are extremely red and fiery-looking to the eyes, setting them apart from all other gemstones. Red diamonds are less than one carat in weight for the most part, and their intense color makes them one of the most expensive precious stones on the planet.
4. Emerald – Up to $305,000 Per Carat
A favorite among royalty since the time of Cleopatra, emeralds are prized for their rich green color and history. While most emeralds contain inclusions (referred to as “jardin”), the best emeralds are flawless and fiery. Colombian-grown is the best emerald, and the best stones are among the priciest of fine jewelry.
5. Ruby – Up to $1.2 Million Per Carat
Also commonly referred to as the “king of gemstones,” rubies are extremely precious because of their rich red hue and two-tiered symbolic association of love, courage, and passion. The most prized rubies, “pigeon blood” rubies, are Myanmar rubies and usually one of the world’s most desirable gemstones.
6. Alexandrite – Up to $70,000 Per Carat
Alexandrite is quite fascinating—color shift from green in daylight to red or purple in light from an incandescent source. The color-shifting stone was first discovered in Russia and now is very difficult to find in quantity or large quality. Because it is so rare, it is the most expensive stones to possess.
7. Musgravite – Up to $35,000 Per Carat
One of the world’s rarest and youngest gems, musgravite was found in Australia in 1967. Graying-green to deep purple, it is a collector’s gem and one of the world’s most expensive precious gems simply because it is so difficult to obtain and so very rare.
8. Paraiba Tourmaline – Up to $16,000 Per Carat
Few gems are more thrilling than the neon blue Paraiba tourmaline. Its vibrant blue coloration is due to copper impurities, and it was originally found in Brazil in the 1980s. The gems are now being mined in very limited quantities, so they are some of the most costly gems per carat weight.
9. Jadeite – Up to $3 Million Per Carat
The finest jade, the jadeite, is economically and culturally prized—particularly in Chinese antiquity. Its most prized, and rarest, variety is a transparent jadeite of bright emerald-green hue, called “imperial jade.” Such rarity and value, together with cultural association of jadeite, render the latter one of the world’s costliest stone.
10. Black Opal – Up to $15,000 Per Carat
Australia’s Lightning Ridge has the world’s finest black opals that are characterized by their dark body and dance-of-color. Black opals are never twice the same, and because of this, they’ve been greatly prized for centuries and are considered some of the costliest gems.
